HL 101 Thermal expansion training panel

The trainer comprises original components as used in heating and sanitation systems and is therefore relevant in practice.
There are five expansion sections. In one of the sections, a compensator can be inserted. The elongation of the pipes is indicated on dial gauges. A force measuring device enables the expansion force to be determined.
